Article excerpt

Introduction

In the thesis (Fujio, 2000) the author provided the necessary knowledge needed to analyze, design, and build information systems. Since the combination of lectures and exercises is important (Felder & Silverman, 1988), the author provided specific examples of sales management design. In thesis (Fujio, 2002), the author provided the technological development format of the basic system of a 3-tier e-business. Further, in thesis (Fujio, 2003), the author performed a study on the theme of "activating the local community using IT", giving 4 specific examples, as well as measuring the efficacy of education.

Regarding graduate research carried out on the basis of the thinking in theses (Fujio, 2000, 2002, 2003), the present treaties shows the measurement results of an analysis of student questionnaires over the past 3 years, and suggests directionality for "practical IT education" through supplemental fieldwork for areas in which the efficacy of education is low.

Deepening of Technology and Expansion of Work

Science and technology have advanced from the past to present with the accumulation and expansion of technology. In education, is it also possible to accumulate and expand knowledge? Specific examples of graduate research are examined hereafter and the possibilities are investigated. Considering Kolb's spiral model (Kolb, 1984), a lifecycle in Barry Boehm's spiral model (Barry, 1988) using Object-Oriented Analysis/Design, is applied in the present treatise. The accumulation of knowledge, the vertical axis of the spiral model (Figure 1), is defined as the deepening of technology. The expansion of knowledge, the horizontal axis, is replaced by the expansion of work. The effect of education in graduate research was also measured according to the level of the students.

Deepening of Technology

Application was made of the accumulation of knowledge, or in other words, the deepening of technology, to the design and manufacturing phase of the lifecycle of an information system construct. The research lifecycle of 1-year is divided into four phases, "Planning", " Environment Development", "Construction", "Evaluation and Paper/Design Specification". The next year research is succeeded by the late research. The technology is deepening step-by-step. The vertical axis of Figure 1 represents the accumulation of knowledge. In order to understand the trial manufacturing system of the previous year, students first acquired basic knowledge about servers, Java, databases, etc., and solved problems from texts and reference books to gain understanding. Next, an understanding was obtained of the architecture used in the trial manufacturing system of existent graduate research, which was developed by its application to the future systems designed in graduate research. Table 1 shows 4 years of examples.

"Year-No." in Table 1 refers to the students, wherein "01-1" refers to the first student graduating in 2001, and "01-2" refers to the second student graduating in 2001. The author extracted the research of two students from each year. It can be seen that student "01-1" in Table 1 designed a client-centered system, using Windows as the OS and Access as the database, and programmed it using Java.

Generally, the student designed trial manufacturing system started as a client centered system and later as a server centered system. The OS on the server was mainly Windows, but Linux was also used. The Java language started with Java and was expanded to JSP and Servlet, and Access was used mainly for the database, but MySQL and PostgreSQL were also used. For the client computers, use was made of mainly Windows PCs, but i-mode cellular phones were also used. As can be seen, as the years passed, the technology deepened and knowledge was accumulated.

The Expansion of Work

The system domain of design and a trial manufacturing in application was applied to the work processed by the information system. …
